“…Magnetic suspension systems can suspend a magnetic body by magnetic force without any contact [7], which requires feedback control in order to be workable. Recently, magnetic suspension systems including active magnetic bearings [S] and also magnetic field control [9] seem to be one of the hot topics in control application field. Nonlinear control approaches are recently focused in this field [3], [SI, [9] …”

AbslractThis paper deals with H m / p DIA control of the magnetic suspension system. H, DIA control is an H , control problem which treats a mired Disturbance and an Initial-state uncertainly Attennation(D1A) and supplies H , controls with good transients. H, DIA controller has a good initial response property, however its robust performance might he improved. We propose H m I p DIA Control which is to find a multi-objective controller to achieve both the H, DIA condition for good initial responsedtransient responses and the structured singular value p condition for robust performance. We apply this proposed approach to the magnetic suspension system, and design a robust controller which has both good properties. Finally experimental results show effectiveness of the proposed control system design framework.

Abstmct-llis paper deals with the H, DIA control system design attenuating initial-state uncertainties and its application to magnetic suspension systems. Here the H, DIA eonbol means B mixed Disturbance and an Initialstate uncertainty Attenuation(Dl.4) control for Linear timeinvariant systems in the infinite-horizon case. The H, DIA control problem supplies H, controls with good transients and assures H-contmls of mbustness against initial-state uncertainties. We derived a necessary and suffcient condition of the generalized H, DIA problem.In this paper, we apply this H, DIA appmch to magnetic suspension systems, and evaluate a mixed attenuation property of the pmposed approach via experiments. We investigate a role of the weighting ma& N for the initial state uncertainty in the control system design.
